PIPE-PULLING MACHINE.

cancer.

To all whom it may concern:

Be it known that I, CLAIR D. SHORTS, a citizen of the United States, anda resident of Fern, in the county of Clarion and State of Pennsylvania,have invented a new and Improved Pipe-Pulling Machine, of which thefollowing is a full, clear, and exact description.

This invention relates to a machine the purpose of which is tofacilitate the placing or removing of the pipe rods or casings of deeplydriven wells, such as oil wells or Artesian wells.

The object of the invention is to provide a machine of this class havingan extensible mast which is adapted to fold down upon the frame of thedevice, the entire structure being mounted upon wheels, so that it canbe readily moved to and from the localities of the Wells.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompany ing drawings forming a part ofthis specifi cation, in which similar characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is a sideelevation of a machine constructed according to my invention, certainparts being broken away; Fig. 1 is a vertical section taken at a pointon the mast, and indicating the manner in which the movable shaft of themast is supported in the guide-mast; Fig. 2 is a plan of the machine;Fig. 3 is a longitudinal vertical section, taken through the machine,and showing the mast in a folded position, a portion of the mast beingbroken away; Fig. 4 is a vertical section through the guide-mast, takenin a transverse plane and showing the other parts in elevation, thisview illustrating especially the means for extending the shaft of themast; Fig. 1 is a side elevation, showing the upper portion of the mastand illustrating a tackle-arm and tackle for pulling the pipe; Fig. 5 isa perspective, showing a portion of the frame and illustrating themechanism for controlling the rotation of the lifting drum; Fig. 5 is aside elevation further illustrating details of the parts shown in Fig.5; and Fig. 6 is a fragmentary sectional view of the ratchet wheel,illustrating a device for rotating the pulling drum by hand.

Serial No. 479,081.

Referring more particularly to the parts and especially Figs. 1 to 3, 1represents the mainframe, which is mounted upon wheels 2, so that itconstitutes a truck or wagon frame, at one end of which a tongue 3 isprovided, to which draft animals may be attached. At the end of the mainframe 1 which is remote from the tongue 3 are provided a pair ofpivotally-disposed posts 41. These posts project nearly vertically, andare disposed at a slight distance apart, as indicated in Figs. 2 and 4.Near their upper ends, these posts are connected by a horizontal shaft5, and this shaft is rotatably attached to the mast-guide or sheath 6 bymeans of a suitable bracket 7 Within the sheath 6 there is mounted toslide longitudinally a mastextension or shaft 8. The sheath 6 is formedof two side bars 9 connected by cross bars 10, and these cross barsguide the shaft 8 in sliding longitudinally in the sheath. On account ofthe shaft 5 which supports the mast, the mast may occupy a horizontalfolded position,as indicated in Fig. 8, at which time its free end issupported on an upper frame or horse 11. As indicated in Fig. 8, thelower end of one of these posts 4: is connected with the rear axle 12 ofthe truck, by means of a plate 13, which plate has a plurality ofadjusting openings 14 therein. These adjusting openings are ada ted toreceive a removable pin 14* which is adapted to engage an opening in thebutt-end of the sheath 6, as indicated clearly in Fig. 1. On account ofthis arrangement, the mast may be held in either an elevated positionwhen the pin is in use; or the pin may be removed to permit the mast tobe lowered to a depressed position.

In order to raise the mast from its depressed position, as indicated inFig. 3, I provide a small elevating drum 15, which is attached in ahorizontal position on the main frame. Rigid with this drum, there isprovided a gear wheel 16, which is adapt ed to be rotated by a pinion 17on a shaft 18,

said shaft being driven by a hand-crank 19, as indicated in Fig. 2.Around this drum 15, an elevating cable 20 is coiled, and one end ofthis cable is attached at 21 to a part of the mast which is above theshaft 5, when the mast is elevated. The other end of the cable runs downunder the axle 12, and is attached to the foot of the mast at 22.Between the drum 15 and the point 21, a

shackle 23 is attached to the cord, the said shackle having a roller 24;which receives the cord as indicated. This shackle is attached to aguy-cord 25, which runs in a nearly horizontal direction over the back26 of the horse 11. From this point, the guycord 25 extendsdownwardly,'and it is anchored in the frame of the truck at 27. Thisguy-cord 25 holds the cable 20 in the manner indicated in Fig. 1 whenthe mast is raised; that is, it holds the cable out of the way of themechanism of the machine, and gives a desirable direction to the upperportion of the cable in pulling the mast down.

Between the axle 12 and the point 22, astrut or strut-bar 28 isprovided. At the lower end of this strut bar, a shackle 29 is attached,having a roller 30 running on the cable 20. The upper end of this strutis pivotally attached to a bracket 31, which bracket is pivotallyattached to the side of the main sheath in an inclined position, asindicated. The strut 28, near its middle point, is provided with a brace32, which brace is pivotally attached at 33 to the under side of theaxle 12, as shown.

In the operation of raising the mast, the drum 15 is rotated in aleft-hand direction, referring to Fig. 3. This takes up the part of thecable below the drum and pays out the part of the cable above the drum.In this way, the butt-end of the mast is brought downwardly, and theupper end raised. The strut 28 not only gives a downward direction orpull to the end of the cable which is attached to the butt-end of themast, but it also produces a downward thrusting force in the strut,which is exerted against the mast on the opposite side of the shaft 5.This facilitates very much the raising of the mast into a nearlyvertical position, in which it can be locked by means of the pin 14?, asdescribed above. When the mast has been brought to this position, alarge block 34-. is placed under the butt-end of the sheath, so as totake the weight off the truck wheels.

Referring now especially to Fig. 1, the upper end of the shaft 8projects above the sheath 6, and it is provided with guy-cables 35,which are carried to the rear and suitably anchored in the ground. Theseguycables are not secured, however, until the shaft 8 of the mast hasbeen raised or extended to an elevated position. In order to enable themast to be extended in this manner, one of the side bars 9 of the sheath6 is provided with an opening 36, as indicated in Fig. 4, and in thisopening a pulley 37 is provided, around which passes a cord 38. Thiscord passes through the opening 36 into the interior of the sheath, andis attached at the point 39 to the shaft 8; that is, it is attached nearthe lower end of the shaft 8. The outer part of the cord extends down toa point near the foot of the mast and is coiled on a shaft-lifting drum-10. This drum is mounted in a horizontal position between one of theposts 1 and one of the truss-frames 41, which are mounted on each sideof the frame 1. This drum 40 is provided with a large gear wheel 42,which is rotated by means of a pinion 4-3 through the medium of ahand-crank 41st. Evidently, by rotating this crank, the cord 38 may bewound up so as to raise the shaft 8 in the sheath 6.

In order to enable the shaft to be supported at a high elevation, Iprovide a shaftseat -15, which is attached by a hinge iii to one of thecross bars 10 of the sheath or guide-mast. This seat 15 is simply ablock, which is adapted to drop down across the interior of theguide-mast or sheath, as indicated in Fig. 1, and when in this position,it will form a support for the butt-end of the shaft, as will be readilyunderstood.

In extending the shaft 8, as (.lescribed, it should be raisedsutiiciently so as to enable the seat 415 to be lowered or set, and theshaft 8 may then be lowered down upon the seat, as will be readilyunderstood. In order to raise and lower the seat 4-5 at will, it isprovided with a rigid arm 47, to which an operating rod or link 18 isattached.

In order to use the mast for pulling the pipes or casings from the well,I provide a large pulling drum 1t). ()n the reduced waist 50 of thisdrum, a cable 51 is coiled, and the end of this cable extends upwardlyand over a large guide-sheave rotatably mounted on the extremity of theshaft 8, as indicated in Fig. 1. From this point, the end of the cableextends do\\'n\\ardl so that it may be attached by means of a suitableshackle 53 to the pipe or rod 5-t, which to be pulled. This drum 49 isprovided with two enlarged sections or drum-collars 5:"), which are ofmuch greater diameter than the waist 50 of the drum. On either of thesecollars, a draw-cable 56 is coiled, and the free end of this draw-cableextends longitudinally of the frame, and is adapted to have horsesattached to it. From this arrangement, when the horses pull on thedraw-cable, the drum lf) rotates and the cable 51 becomes coiled up onthe waist 50 of the drum. In this way, the pulling cable or line 51 willbe taken up so as to raise or pull the pipe If it is not desired toattach the pulling cable 51 directly to the pipe, I may employ a fall ordead-line 57, which is simply a loop which passes down to the pipe, asindicated in Fig. 1, passing through a guide block 58, the fixed end ofthe dead-line being attached by means of a hook 59 to the extremity ofan arm 60. This arm (it) is formed of two bars (31 and 62, which arepivotally attached together at their outer ends. The

lower bar 62 is attached by a removable pin ii 63 to the side of theshaft 8, and I provide a plurality of openings in the side of the shaft8, in any one of which the main pin 63 may be attached. By removing thepin 63 to a lower opening, the arm 60 will project farther from themast, and this arrangement will enable the direction of pull of the deadline to be adjusted with respect to the pipe without necessitating themoving of the entire apparatus. The bar 62 is made long enough so thatit extends at its upper ext-remity beyond its point of connection withthe bar 61. In this way a projection is formed over which a loop may behung in case the cable is not provided with a hook. The upper end of themast is provided. with eyes 60 by means of which side guy wires may beattached.

In order to brace the mast against lateral force, I provide diagonalbraces 65, which are attached as indicated in Fig. 4, the upper endsbeing rigidly secured to the sides of the sheath, and the lower endsbeing pivotally attached to eye-bolts 66 on the truss frames 41.

I provide means for operating the drum 49 by hand. For this purpose, theshaft 67 of this drum is extended so as to project beyond the trussframe on one side of the machine, as indicated in Fig. 1. To thisextension of the shaft, I attach a crank 68, which crank may be directlyrotated by hand by means of its handle 69. At a suitable point on thecrank 68, a link 70 is pivotally attached, and to the outer portion ofthis link a rocker arm 71 is pivotally attached. The details of thisrocker arm and the means for rocking it are illustrated in Fig. 5. Atone end, the rocker arm has a wrist 72, which is rotatably mounted in abearing 73 on one of the frame bars 74. Beyond the bearing 7 3, thewrist 72 is formed into a radially extending plate or wing 75. In orderto swing the rocker arm to and fro, I provide a lever 76, which consistssimply of a long bar, the one extremity of which is bifurcated so as toform a heartshaped yoke 77, and beyond this yoke the sides of the yokeare extended so as to form a double or bifurcated tongue 78. Between thebars of this tongue 78, a narrow throat 79 is formed. This throat isadapted to receive the wing 75, so that if the lever 76 is rocked to andfro, the rocker arm 71 will also be swung to and fro. The rocker arm 71is provided with several openings 80, in any one of which a removablepin 81 is placed, for connecting the rocker arm to the link 70, as willbe readily understood. This gives the desired adjustment to the rockerarm with respect to the crank 68.

On the under side of the tongue 78, a notch 82 is formed, and this notchis for the purpose of enabling the lever 76 to be supported in aninoperative position. For this purpose, I provide a rest 82, which is inthe form of a bracket attached to the frame bar 74-. This rest presentsa vertical slot 83, and the lower edge of this slot is adapted to engagethe notch, so as to support the tongue, when the ton ue has beendisengaged from the wing T5. In this connection, it should be understoodthat the tongue is removable from the wing, and it can be hung at oneside with the notch supported on the bracket. hen it is desired toattach the lever, the heart-shaped yoke is placed over .the wing 75, andthe lever is then pulled away from the wrist 72 until the wing seats inthe tongue. With this arrangement, it will be evident that the lever 76can be readily thrown into or out of operation, and it will be alsoevident that by rocking the lever 76 backward and forward, the rockerarm 71 will move backward and forward, so as to rotate the drum. Inaddition to this, I provide detent means for holding the pulling drumagainst a backward rotation. This detent device operates as a means forenablingthe drum to be slowly rotated. The details of this mechanism aremost clearly illustrated in Fig. 6, but they are also shown in Fig. 1.

On the end of the drum 49, a ratchet wheel 84 is provided, the teeth ofwhich incline towar the right, as shown. On the adjacent truss frame, arocking plate 85 is pivotally mounted on a pin 86, said pin beingsecured in a suitable bearing 87. This rocking plate 85 is formed of twooppositely-disposed plates, between which a pair of pawls 87 and 88 aremounted.

, These pawls extend over toward the ratchet wheel.- The upper one isthe longer of the two, and both pawls have nibs at their extremities,which engage the teeth of the ratchet wheel, as indicated. The rockingplate 85 is further provided with a lever 89, by means of which it maybe rocked on the pin 86. The pin 86 is located between the pawls 87 and88, so that, when one advances the other recedes. From thisarrangernent, it will be evident that by rocking the lever 89 up anddown, these pawls 87 and 88 will rotate the drum. During this operation,as one pawl is rotating with the ratchet wheel, the other pawl will beslipping back of the teeth of the same, so i as to give a new hold. Thisrocking plate is provided with extra openings 85 which may removablyreceive the pivot pins 85 which attach the pawls to the rocking plate.The rocking plate is also provided with pins 85 which support the pawlsif the lever 89 is held down so as to disengage the pawls from theratchet teeth. The openings 85 are different distances from the pivotpin 86 so that the leverage of the pawls may be varied to travel asdesired.

On one end of the drum 419, a brakewheel 90 is provided, and thisbrake-wheel paid out.

tending to prevent the rotation of the drum.

mast can be quickly elevated and a tackle is provided with a brake-band91 which passes around the same. One end of this brake-band is'securedto a lever 93 at 92, as indicated in Fig. 1. The other end of the bandis attached to another arm of the lever 93, which is mounted on theframe so as to rock at the point 94 between the arms of the lever. henthe long arm of the lever 93 is forced downwardly, the brakeband will betightened on the brake-wheel, so that a frictional resistance ispresented,

This lever may be held in a depressed position by means of a hook 95,which runs freely on a guide-bar 96 attached to the frame, as indicatedin Fig. 1. lVhen this hook is engaged over the lever 93, it holds itagainst rising. In this connection, it should be understood that thehook 95 projects from a ring which runs loosely on the guide 96, so thatthe ring binds itself when force is applied to the lever.

While I have illustrated only one of the seats 45 for supporting theshaft 8 in an elevated position, more of these may be provided, ifdesired, at different elevations. In this way the shaft 8 may besupported in any number of diflerent extended positions. In this way,the height of the mast can be regulated, as desired.

A machine constructed as described can evidently be readily transportedfrom place to place like an ordinary wagon, and the adjusted by apulling operation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
